When you’re searching health-related articles online related to testosterone, you may have heard the term D-Aspartic Acid. This amino acid is one of the forms of testosterone given during testosterone replacement therapy. But you may not know why.
D-Aspartic Acid is high in vitamin D. A deficiency of vitamin D has been linked to low testosterone. However, though this information has been known for some time, new studies performed by two Danish researchers indicate that Vitamin D and low testosterone may be more closely linked than previously believed.
We get the majority of our vitamin D from sunlight, food and supplements. For most men, increasing how much vitamin D you take may not change your testosterone levels significantly. But men who already have low testosterone may benefit from vitamin D supplements, which can boost testosterone and even aid in fertility.
That’s at least what the new Danish study concludes, which links the production of testosterone to the concentration of vitamin D in the blood. What’s new in the study is that vitamin D is directly linked to the production of testosterone.
The link is clear, however it’s still speculative whether supplements are the solution.
In the study, two groups were put together. The first was made up of 41 men who had had one testicle removed due to testicular cancer. The second was 300 healthy young men.
The researches took blood samples from each, measuring testosterone concentrations, Vitamin D, luteinizing hormone (LH) levels, and the parathyroid hormone, which regulates calcium. Putting the parathyroid next to the vitamin D gives researchers a clearer view of the body’s full Vitamin D levels. The testosterone and LH provide insight into the pituitary gland and testicular function.
The researchers discovered that men with less vitamin D had less positive reactions to injections of testosterone than men with higher vitamin D.
Furthermore, vitamin D may increase the effect testosterone has fighting osteoporosis and general bone health.
To summarize, as that was a lot of medical jargon, taking Vitamin D supplements can help a man keep a higher concentration of testosterone and have other positive effects as well.
Can It Help Infertility?
Researchers also looked into what Vitamin D for infertile men. Could, for instance, vitamin D make the testicles produce testosterone?
Taking some testisticular tissue from one of the cancer survivors, the doctors cultured some healthy, noncancerous tissue in a lab. They then applied some activated vitamin D to the tissue. The exposed tissue produced more testosterone than the unexposed.
So yes, it appears that vitamin D aids in testosterone production naturally. They are currently waiting to learn if vitamin D can improve fertility as well. It would stand to reason, as testosterone is responsible for producing the viscous substance that sperm lives in known as semen, however the results aren’t in.
There are benefits to just good old fashioned vitamin D supplements, but they may not be enough. Often, testosterone replacement therapy may be necessary, though there are health risks that one should consider along with the benefits.
